Hi, I need a detailed and proper answer of this questions. Please provide references with answer.

Question 1

The use of E-Commerce has benefit the sale of many products ranging from the increase of airline tickets purchased online, the booking of hotel rooms online as well, as well as the success of eBay and Amazon. Yet there are many other products that will never take off online such as the grocery purchase from supermarkets (cheap products) as well as the sales of fashionable clothing or even perfumes (expensive products). Discuss why are some products are easier to sell online than others.
